Difficult to say without seeing and handling the gun, knowing the model number and year of manufacture, barrel length, etc... Much of the value would be in the condition of the finish and the operation of the action.

A quick search of references turns up prices from $250 for excellent condition and on down for lesser conditions (various models and finishes averaged). Even so it depends on who is doing the buying as to how much they would be willing to pay at the moment.
